Dragon Has Nine Sons

They say that Dragon has nine sons in Ming Dynasty.
The Dragon sent its nine sons to help the first emperor to conquer China. After
completing the mission, nine dragons were preparing their journey to
return to heaven. But the emperor played a trick on the most powerful dragon, the 6th son,
to carry a magic stele with a carved inscription, which could suppress
any ghost, spirit or evil creature. The 6th dragon couldn't move under
the magic stele, and all of his other brothers wouldn't leave without
him. However, they wouldn't work for the emperor anymore. They decided
to no longer show their dragon identities and turned themselves into evil creatures.
